 For the moment, the best solution is to provide the same image uuid for
 both image_ref and image_ref_alt. Tempest will skip tests as needed if it
 detects that both images are the same.
+
+Unit Tests
+----------
+
+Tempest also has a set of unit tests which test the tempest code itself. These
+tests can be run by specifing the test discovery path::
+
+    $> OS_TEST_PATH=./tempest/tests testr run --parallel
+
+By setting OS_TEST_PATH to ./tempest/tests it specifies that test discover
+should only be run on the unit test directory. The default value of OS_TEST_PATH
+is OS_TEST_PATH=./tempest/test_discover which will only run test discover on the
+tempest suite.
+
+Alternatively, you can use the run_tests.sh script which will create a venv and
+run the unit tests. There are also the py26, py27, or py33 tox jobs which will
+run the unit tests with the corresponding version of python.
